mysql5.7.18.1修改用户密码报错ERROR 1054 (42S22): Unknown column 'password' in 'field list'解决办法

本意向修改一个用户的密码，网上搜到的命令为如下

mysql> update user set password=password(“新密码”) where user=”用户名”;

执行后报错 　ERROR 1054(42S22) Unknown column 'password' in ‘field list’

错误的原因是 5.7版本下的mysql数据库下已经没有password这个字段了，password字段改成了authentication_string

所以请使用一下命令：

>mysql -u root -p
Enter password: ********
